Each active domain name is registered on the name of a particular person and through the registration procedure a number of details are submitted - the owner’s names, address, email, mobile phone number, and so forth. This information in addition to the registrar company name and the registration/expiration dates is called WHOIS of the Internet domain and in agreement with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and correct. If a domain address has invalid WHOIS details, it could be reported and if the details aren't corrected, the domain address may be erased or the registrar company could take over its ownership. By default, the WHOIS information is public and may be seen on many lookup sites, or for a small number of country-code extensions - on the websites of the respective Registry organizations. All companies that provide registration services are required to provide an uncomplicated way for their clients to access and edit the WHOIS information of any domain address they own as much as the particular TLD allows it.
